The Rangers unabashedly are going to ride this one out for as long as they can.

Because when a wave of positivity this tall comes, showing such immense potential, there is little to do besides enjoy it.

Eventually, nights like the 5-0 win over the Blues on Tuesday at the Garden are going to seem like far-gone memories. But this team is doing what it can to imprint how it did it more than the result itself — and that is where the lasting impressions can be made.

“It’s a happy group,” forward Chris Kreider told The Post after he had two assists in his return from a four-game absence because of neck spasms. “I think we like winning. But at the same time, it’s a long season here and there are going to be points of adversity. It’s good to use this stretch here as an example of how we want to play.”

It has been the vast majority of the Rangers’ 7-3-0 start that can be used as an example of how they want to play. They now have more than 40 goals (41) in the first 10 games for the first time since 1992-93. With Kreider back in the lineup, one of the fastest groups in recent memory got even faster, just flying past the Blues (5-3-2), who were rested and ready, unlike the Lightning, who were whooped 6-1 by the Rangers on Sunday.

“It’s been a great start to our season here,” said goalie Henrik Lundqvist, who got a much-needed great game out of himself, stopping all 35 shots he saw for his first shutout of the season, extending his franchise record to 60. “A lot of times it starts in our own end, how we break out. That’s really how you get speed to your game — that first pass, close support. I’m super impressed.”

It is hard not to be, with a run of 5-1-0 over the last six.

With Kreider’s return, the team now has four forward lines that all can skate and score. The power play went 2-for-6 against the league’s second-best penalty kill.

They never let St. Louis establish its heavy forecheck, as the Rangers’ defense moved the puck so quickly out of its own zone that it looked easy. It wasn’t. It’s just that the defense has improved by such leaps and bounds from last season that it’s astounding, and the forwards are helping out by “pouring back,” as Kreider described it.

“We have guys that are making plays like they have a ton of confidence and swagger,” alternate captain Marc Staal said. “Even defensively, we’re making confident plays in our own end and it’s allowed us to get out of our end zone quickly and create those chances quickly.”

The chances came fast and furiously. Dan Girardi got a four-on-four goal that came on a deflected shot 9:37 into the first, and 94 seconds later, Harvard rookie Jimmy Vesey got his team-leading sixth goal of the year on a power play. The 2-0 first-period lead was preserved with a terrifically athletic glove save by Lundqvist on a Robby Fabbri breakaway.

“This was his best game so far this year, there’s no doubt,” coach Alain Vigneault said, as Lundqvist also stopped Colton Parayko on a second-period breakaway, moments after Rick Nash had given the Rangers a 3-0 lead. “The difference was Hank made those two breakaway saves, and when we had opportunities, we were able to capitalize.”

That continued in the second period when Mats Zuccarello finished on a power play at 12:55 — coming on a beautiful close-quarters pass from Kreider. Then Kevin Hayes continued his torrid start by finishing an expertly executed three-on-one break for his third goal of the year at 18:17, making it 5-0.

“We have confidence in our system and one another, and we believe in it and try to execute it,” Lundqvist said. “We will just try to build on this.”
